As the debate rages over what forms of energy generation pose acceptable risks and rewards, the Dept. of Interior's Bureau of Reclamation is boosting the prospects for hydropower. The agency released a report March 31, 2011, that highlights 70 existing dam, diversion structure, and other waterway operations in 14 Western states that could be expanded to generate more electricity.

The potential increase in total power is modest, estimated to be enough to supply about 85,000 households. But such projects could have local appeal, depending on choices being made between various energy sources.
